In spite of this, the preparation of thiol-end functionalized PMMA was achieved by introducing a short block of polystyrene after the RAFT polymerization of MMA.Third, RAFT technique was applied to design and synthesize some well-defined poymers. Five monomers, lauryl methacrylate,(N,N-dimethylamino)ethyl methacrylate, poly methyl ether methacrylate, 4-(4\'-cyanobiphenyl-4-yloxy) butyl methacrylate and 2-ethyl methacrylate were chosen to RAFT homopolymerization or copolymerizations mediated by cumyl dithiobenzoate.
RAFT方法在具有特定结构聚合物的设计与合成上的应用,在机理研究的基础上,本论文选择五种不同结构的甲基丙烯酸酯类单体:lauryl methacrylate,(N,N-dimethylamino)ethyl methacrylate,polymethyl ether methacrylate,4-(4'-cyanobiphenyl-4-yloxy)butyl methacrylate和2-ethyl methacrylate,用CDB调控RAFT聚合的方法设计合成了一些特定结构的聚合物,详细而深入地研究了它们的均聚、共聚动力学,发现了双硫酯并非在聚合反应初期就全部转化,而是随着反应进行逐步消耗,这与理想的活性聚合体系有很大差别。

The silicon-acrylic latices with core-shell structures were prepared by means of a"two-stage"emulsion copolymerization. The effect of constituents and proportion of core and shell parts on the properties of latex film were investigated, and their applications in water-borne wood coatings and elastic coatings were explored. The results indicate that wood coating and elastic silicon-acrylic coatings with good performance and zero VOC content can be prepared by suitable design of structure of silicon-acrylic latex particles.
